Hot Jupiters do not rule out alien Earths
(Mar 31, 2006)
Habitable, Earth-like planets can form even after giant planets have
barrelled through their birthplace on epic migrations towards their
host stars, new computer simulations suggest. The finding contradicts
early ideas of how planets behave and suggests future space missions
should search for terrestrial planets near known "hot Jupiters".

Life waxes and wanes with bobbing of the
Solar System
(Mar 31, 2006)
The solar system's up-and-down motion across our galaxy's
disc periodically exposes it to higher doses of dangerous cosmic
rays, new calculations suggest. The effect could explain a mysterious
dip in the Earth's biodiversity every 62 million years. The solar
system moves through the Milky Way rather like a child on a merry-go-round.
It completes a circuit of the galaxy once every 100 million years
or so but as it goes it bobs up and down through the dense galactic
disc. Previous research had suggested this motion might affect Earth's
climate as the solar system passes through the giant hydrogen clouds
concentrated in the galaxy's spiral arms.

Heat-loving bug find in Antarctic
(Mar 30, 2006)
Researchers have found traces of a heat-loving bacterium that may
live beneath a frozen lake in Antarctica. Lake
Vostok is covered by more than 3km of ice and must have been isolated
from our planet's atmosphere for millions of years. The bacteria appeared
in sediment mixed with a core of ice drilled by Russian and French
researchers. The heat-loving, or thermophilic, bacterium may suggest
that hydrothermal vents exist on the lake floor.

NASA releases new maps of Jupiter
(Mar 30, 2006)
The US space agency has released the most detailed colour maps of
the planet Jupiter
ever produced. The stunning maps were pieced together by researchers
from images taken by the Cassini spacecraft as it approached Jupiter
on 11 and 12 December 2000. Raw images exist in only two colours so
the maps were coloured to show how Jupiter would appear to the naked
eye. They consist of one cylindrical map of the planet along with
north and south polar maps of Jupiter.

Moonlets hint at Saturn's violent past
(Mar 30, 2006)
The propeller-shaped footprints of four tiny moonlets have been detected
in Saturn's rings
– adding weight to a theory that the rings formed when a larger
moon exploded. The moonlets are no more than about 100 metres across,
which makes them the first known objects of intermediate size to be
found in the rings. They fall between ordinary ice-balls of up to
10 metres and a handful of more substantial moons a few kilometres
across. The telltale patterns appear in old images taken by the Cassini
spacecraft when it entered orbit around Saturn in July 2004.

Your secrets are safe with quasar encryption
(Mar 29, 2006)
Intergalactic radio signals from quasars
could emerge as an exotic but effective new tool for securing terrestrial
communications against eavesdropping. Japanese scientists have come
up with a method for encrypting messages using the distant astronomical
objects, which emit radio waves and are thought to be powered by black
holes. Ken Umeno and colleagues at the National Institute of Information
and Communications Technology in Tokyo propose using the powerful
radio signals emitted by quasars to lock and unlock digital communications
in a secure fashion.

NASA restarts once-dead Dawn asteroid
mission
(Mar 28, 2006)
Less than a month after falling victim to budget and technical concerns,
the Dawn asteroid explorer was brought back from the grave Monday
by a decision to restore funding to the mission and launch the probe
by next summer. NASA announced the reinstatement, a complete reversal
of the decision three weeks ago to kill the mission, after an appeal
from project officials at the Jet Propulsion Laboratory. The objections
prompted yet another review of Dawn, which had undergone a series
of investigations since October that assessed the state of the mission
after various problems and cost overruns came to light.

Cannibal stars like their food hot, XMM-Newton
reveals
(Mar 27, 2006)
ESA’s XMM-Newton
has seen vast clouds of superheated gas, whirling around miniature
stars and escaping from being devoured by the stars’ enormous gravitational
fields – giving a new insight into the eating habits of the
galaxy’s ‘cannibal’ stars. The clouds of gas range in size from a
few hundred thousand kilometres to a few million kilometres, ten to
one hundred times larger than the Earth.

Fire caused SpaceX rocket failure
(Mar 27, 2006)
A fire fed by a fuel leak caused the failure of a commercial rocket
seconds into its maiden launch, the company that built it has confirmed.
SpaceX's Falcon 1
rocket was lost during lift-off from an island in the Kwajalein Atoll
in the Pacific Ocean. It was carrying a US Air Force Academy research
satellite onboard.

Bright future for Sun's twin
(Mar 27, 2006)
It looks like a home away from home. Astronomers trawling through
a catalogue of known stars have found one that is nearly identical
to our Sun, and they say it's an ideal place to start looking for
small blue-green planets that could host alien life. The solar twin,
called HD 98618, lies about 126 light years from Earth, and is bright
enough to be seen from the Northern Hemisphere using binoculars.
